Last year, fusion energy startup General Fusion was struggling to raise money and laid off employees At least 25% of its employees before Received a lifeline investment of $22 million While I figured out how to keep the company afloat.
Today, General Fusion revealed its survival plan: It will go public through a reverse merger with a special purpose acquisition company. Valley of the Third Springin addition to additional investments from institutional investors. It’s a major change in fortunes for the company whose CEO wrote a public letter last year asking for funding.
If the deal closes as planned, General Fusion could receive up to $335 million from the deal, more than double what it was said to be seeking to raise last year before receiving the $22 million lifeline.
General Fusion said the deal would value the combined company at about $1 billion. Before announcing the merger. Startup Fusion, founded in 2002, has done this before It raised more than $440 millionaccording to PitchBook.
General Fusion plans to use the funds to complete its experimental reactor, Lawson machine 26 (LM26). The device uses a technique called “inertial confinement,” which works by compressing the fuel pellet until its atoms fuse together, releasing energy in the process. The National Ignition Facility has used inertial confinement in its work Successful integration experiencesUsing laser beams to bombard fuel pellets to unleash compressive force.
However, the LM26 avoids the use of lasers. Instead, it uses steam-powered pistons that push a wall of liquid lithium metal inward to compress the fuel pellets. This liquid lithium then circulates through a heat exchanger, which generates steam to power the generator. By avoiding the use of expensive lasers or superconducting magnets, required in other fusion reactor designs, General Fusion hopes to build a fusion power plant at a lower cost. But first the company must prove that its approach is workable.
Last year, before revealing its financial woes, General Fusion said that in 2026, LM26 would reach scientific break-even, where the fusion reaction generates more energy than is needed to get it started. Scientific breakeven is a key milestone, although different from and easier to achieve than commercial breakeven, as fusion reactions release enough energy to export electricity to the grid. General Fusion did not respond to a request asking if its schedule had changed.

The buyout firm, Spring Valley, specializes in reverse mergers with energy companies. It previously took NuScale Power, a small modular nuclear reactor company, public in a deal whose stock price has since fallen more than 50% from its peak last year. The company is also in the midst of completing a merger with Eagle Energy Metals, a uranium mining company that is also supposed to develop its own SMR.
General Fusion is not the first merger company to go public. In December, TAE Technologies announced it would do so Merger with Trump Media and Technology Group In a deal, the combined company is valued at more than $6 billion.
The common thread that connects these deals is, of course, data centers. They are expected to consume Nearly 300% more energy by 2035according to BloombergNEF, and General Fusion explicitly cite high power demand in their data centers Merger announcement.
But the company also pointed to broader electrification trends, including electric vehicles and electric heating, which could increase overall electricity demand by up to 50% by 2035. It’s a reminder that while the Trump administration has cast doubt on an electrified future, other countries are moving forward. While General Fusion may face technological challenges, trends in the energy world suggest that if it can provide nuclear fusion power at a reasonable cost, it will find plenty of willing buyers.
